I can only say that its a hang phone and its too costly you all should increase the r and internal storage too hang I suppose it should be better if you make the phone cheaper and put lots of ram on it ok. Hope we can even achive a very good app file etc .while I waa using this phone it hangs too slow and one most very important thing is that my jio sim does not call when it if offline I mean if it is the internet off that it does not work what a useless phone I had this phone it should have upgrading facility too and the last and the least may this phone good to sell
